From the very first glance, the intensity is undeniable. This is not a soft or diluted tone. The blue presents itself with strength and clarity, concentrated within the body of the crystal and expressed with remarkable confidence. It is a colour that does not need light to exist, yet responds to it with a vivid internal activation that gives the entire specimen a luminous presence. The crystal develops in a well defined prismatic structure, with clean vertical edges that guide the eye along its natural growth. These vertical faces act as channels for light, creating subtle reflections that move across the surface and through the interior. This interaction enhances the perception of depth and reinforces the internal colour without breaking its continuity. At the base, the crystal shows a natural semi termination, preserving its original formation while adding character to the overall structure. This detail does not interrupt the visual balance of the piece. Instead, it confirms its authenticity and geological integrity. The dominant tone sits firmly within the Paraíba spectrum, a vibrant electric blue with only very slight greenish nuances appearing softly in certain areas. These nuances remain secondary and never compete with the primary chromatic identity of the crystal, which remains clearly blue and highly saturated. Internally, natural features are visible, subtly tracing the history of the crystal’s formation. These do not distract from its visual impact. On the contrary, they provide depth and reinforce the fact that this is a natural, untreated specimen formed under precise geological conditions. The presence of copper within the crystal structure is what gives rise to this exceptional colour. This element, rarely incorporated into tourmaline, is responsible for the distinctive intensity that defines Paraíba material. It is not a surface effect, but a structural property that gives the colour its permanence and strength. Compact in size yet powerful in expression, this crystal delivers exactly what defines Paraíba tourmaline: intensity, structure and unmistakable identity.

The combination of a well structured prism, strong saturation and visible natural features makes it a balanced piece from both an aesthetic and mineralogical perspective. Its value lies not only in the colour itself, but in the way that colour is carried through the crystal with consistency and presence. Even at a smaller scale, it maintains a level of intensity that is immediately recognisable. Lapidary Potential: The internal colour and zones of transparency indicate that selective cutting could produce a vivid small gemstone. However, doing so would remove the natural prismatic form and the structural identity of the crystal. In its current state, the specimen preserves both its morphology and its chromatic character, offering a complete and authentic representation of Paraíba tourmaline. ————- Shipping and Handling: All orders are shipped by Portuguese National Post and UPS. • Dispatch time: within 1 to 3 business days after payment confirmation to Catawiki • Transit time service: between 2 to 5 business days within europe and worldwide, depending on destination national post. • A tracking number is always provided Photography and transparency: All photographs are taken under controlled lighting conditions using a macro lens, carefully selected to present each specimen as accurately as possible. No filters, colour enhancement, or artificial saturation are applied. The lighting setup uses a calibrated 5500K light source, replicating neutral daylight to reveal natural tones, surface features, and internal characteristics. Under warmer or weaker indoor lighting, colours may appear slightly different, which is normal. The purpose of this photographic process is documentation and representation, not visual enhancement. Images are intended to reflect the specimen faithfully as it appears under balanced natural light conditions. Identification and ethics: All specimens offered are natural and described to the best of our knowledge, based on direct sourcing, professional experience, and information provided by trusted suppliers working at the origin. Every effort is made to ensure transparency and accuracy regarding identification, locality, and general characteristics, avoiding misleading statements about treatment, provenance, or nature. Customs and import taxes: Any customs duties, import fees, or local taxes applied by the destination country are entirely the responsibility of the winning bidder. These charges are not included in the auction price or shipping cost and are determined by the buyer’s local authorities. Guarantee and resolution: Customer satisfaction is important. In the unlikely event of an issue such as loss, damage, or discrepancy, please contact us promptly through Catawiki’s messaging system. Each case is handled individually and fairly, with appropriate solutions offered when justified. Appreciation and commitment: We sincerely thank you for your trust. Our work focuses on careful selection, accurate representation, and respectful presentation of mineral specimens with character and interest. Each piece is chosen for its individual qualities rather than speculative or financial considerations. We aim to provide a transparent, reliable, and consistent experience for collectors at all levels. With gratitude, GemPulse Minerals
